Hash Hashemian: Visionary leadership
As Dr. Hashem M. “Hash” Hashemian prepares to step into his term as President of the American Nuclear Society, he is clear that he wants to make the most of this unique moment.
A groundswell in public approval of nuclear is finding a home in growing governmental support that is backed by a tailwind of technological innovation. “Now is a good time to be in nuclear,” Hashemian said, as he explained the criticality of this moment and what he hoped to accomplish as president.

In the spherical-harmonics component form of the Boltzmann equation for a cylindrical system with radial symmetry and z-dependence, application of the commonly applied boundary conditions gives rise to more equations than there are unknowns. This paper considers selected combinations of the equations resulting from the application of these radial boundary conditions for the P3 approximation. Numerical evaluation of the angular flux at a free surface and at an interface between two different media shows that a combination of equations which closely satisfies the desired conditions is that suggested by Davison.
